A friend of mine owns a very deep, often scratchy voice and a speech defect that makes all her r's throaty and harsh. She likes to make a good use of it, often dropping into growl when she's angry - people tend to quickly find something important to do somewhere else when they hear her talk like this.

I had this dream.\\ I dreamt that I was walking past this group of derelicts and some of them talked to me. Suddenly one of them brushed past me and my pockets felt lighter. He laughed, showed me my wallet and hared off. I didn't follow him because I knew I'd never catch him. I just let the frustration at not being able to follow him, the shock, violation and anger at the impropriety (and losing £50) well up, then I turned to his confederate, whom my friends had caught.\\ "Is this her?" They nodded. She sullenly averted her eyes and said something.\\ What came out of my mouth next was a voice so scary one of my friends flinched in shock. Imagine a dry, harsh rasp, such as might come out of the throat of a mummy, not deep, but with a hint of bubbling, rotting corpse larynx and a touch of a swarm of a million flies. Now imagine that they are displeased with ''you''. I truly sounded like I was possessed or like an EldritchAbomination; I could have auditioned for the part of Nurgle. Yet I never raised my voice at all.\\ "TELL ME WHERE HE IS"\\ The lady started, and began to shiver. She could barely get the words out she was that scared.\\ "I- I- don't know..."\\ "TELL ME WHERE YOUR BOLTHOLES ARE"\\ "Boltholes, w-w-what?"\\ "WHERE MIGHT HE HIDE? WHAT WOULD HE DO WITH THE WALLET?"\\ She was turning her face away as if she couldn't bear to look me in the eye. I must have seemed diabolical.\\ At that moment one of my other friends arrived with the thief in tow. I sighed in relief and decided to use that £50 to buy everyone who had helped me drinks. It was only fair. :-)

This troper managed (while still able to speak like an alto: I'm a guy and I was 13 when I did this) to speak in a very funny deep voice while performing as Ghengis in Dracula Spectacula. Every time he did it (when he had to say "Nobody understands me."), the audience laughed.

This troper once somehow dropped into a somewhat terrifyingly deep voice whilst mock-threatening his brother. Said sibling was more than a little freaked out, as was he.

This troper used to have a very deep voice by default due to years of being a shrinking violet leading to lax vocal cords. I became more audible and my voice became more normal. When I invoke my old voice it's always a low, rumbling, slightly gravely but still smoothe tone and always used for a running joke that I'm secretly a murderous evil overlord. It inevitably ends with me singing "We will all go togeather when we go." for some reason, not sure why.

This ''female'' troper does this. Seeing her default voice when talking to a stranger or recently-made friend is cutesy and rather high, seeing her get furious and drop into something that really sounds like it should belong to a man is... jarring. The fact that her evil voice is rather hammy dosen't help.

This troper deliberately pitches his voice to a higher, 'Normal' tone when talking to people he's just met so he doesn't scare them. Once he gets to know them, he'll dial it back to his normal voice [which is this trope] over time. However, that's not all- When angry, his voice drops to what one of his friends once called 'The Devil Growl'. He can also call 'The Growl' up at will, but it's generally somewhat less impressive when he's not scowling.

Another thing- The same troper was working as a Telemarketer. Because of aforementioned deep voice, he deliberately pitched his voice to a higher pitch then normal most of the time. During one call, he was asked by an irritated gentlemen to 'Drop the fake voice'. As the gentleman hadn't been terribly polite during the call, the troper gleefully switched to his normal voice and said "You mean like this?" While obviously the response could not be seen, if one were to go back and listen they would hear a small 'Eep!' and the sound of a phone being fumbled and dropped before the call was hung up.

This Troper also (unconsciously) hightens his voice to not-intimidate others. Its such that when I speak in my casual voice, not even forcing it deeper, my mom told me to 'stop that'. The relevant part is when I hail a friend from behind. #QUOTE#''Me'': '''Hey.''' #QUOTE#''Friend'': SATAN! *spins around* Oh, hey. I thought you had come to reap my soul to hell, or something. #QUOTE#''Me'': Just saying 'Hi'. #QUOTE#''Friend'': Hey, say "look, I am your father"! #QUOTE#''Me'': No. I've been getting that request since fifth grade. #QUOTE#''Friend'': Come on~. #QUOTE#''Me'': *Sigh*'''Luke'''.*Breather Effect*. '''I, am your father'''. #QUOTE#''Friend'':eeee~

This female troper has a deep-ish voice. She reflexively pitches it higher and tries to speak in an airy tone when talking to strangers so they don't think she's going to eat them. She likes to talk in demon voices when nobody's listening to amuse herself, though.

I'm an inversion! My natural voice is a very high Soprano but I started training it to sing Alto a few years ago {also when I listened to recordings I felt like I was eight}. So now my voice is an alto {albeit a higher one} and people thought I was eviller with the high soprano. I do switch to a growl when I'm angry though and I have a demon voice that's incredibly high and for some reason British that I use for comic effect. Or scaring my 15 year old friend.
